The feedrate override can be defined via the PLC in binary or Gray coding.
With binary coding, the feed value is interpreted in %.
0% to 200% feed changes are possible, in accordance with the binary value in the byte.
The following permanent assignment applies:
Binary values > 200 are limited to 200%.
The machine data:
MD12100 $MN_OVR_FACTOR_LIMIT_BIN (limit for binary-coded override switch)
can be used to additionally limit the maximum feedrate override.
With Gray coding, the individual switch settings are assigned to the following code.
